SPECIFICATION forming part of Letters Patent No. 754,480, dated March 15, 1904.

Application led July 16, 1902. lSerial No. 115,805. (No model.)

To and whom t may concern,.- V Be it known that I, J oIIN D. MoRAN, a citize of the United States, residing at St. Paul,in the county of Ramsey and State ofMinnesota, have invented certain new and useful Improvements in Excavating-Machines, of which the following is a specilication.

My invention relates to improvements ineXcavating-machines, and is designed particu- Io larly for the excavating of ditches and sewers. My invention consists in the features of construction and combination hereinafter particularly described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of my improved excavating-machine shown in operation. Fig. 2 is a section on line w of Fig. 1. Fig. 3 is a plan view of the machine. Fig. 4: is a front elevation. Fig. 2o 5 is a rear elevation. Fig. 6 is a section on line y y of Fig. 1, and Fig. 7 is a detail of the support for the runway.

In the drawings, A represents the supporting-wagon of the machine, providedwith car- 2 5 rying-wheels 2. Carried by the wagon A is the base 3 of the eXcavetor-framework, upon which are supported the standards 4F, 5, and 6. Fulcrumed upon the shaft 7 is a runway B, the ends of said shaft having journal-sup.

3o port 31 in the upper ends of the standards L1.

Journaledin the lower and upper endsof thev runway are the shafts 8 and 9, upon which are mounted sprocket-wheels 10 and 11, respectively. Chains 12 run over said sprocket- 3 5 wheels. Asprocket-wheel 13 upon'one end of the shaft 9 is connected by a chain 14 with the sprocket-wheel 15, mounted upon one end of the shaft 7. Upon the opposite end of the shaft 7 is mounted a sprocket-wheel 16, con- 40 nected by a chain 17 with a sprocket-wheel18,

A wing or apron 23 has hinge connection 24: 50 with the lower end -of said guideway and is adapted to rest at its lower end upon the ground, as shown in Fig. 1.

In order to support the runway B at the desired angle, I provide the telescoping rods 25 5.5 and 26, connected with the sides of the runway and base of the framework, respectively, as shown in Fig. 1.

Supported between the standards 5 and 6 below the upper end of the runway is achute 27, the lower end of the chute being provided with a hinged door 28, adapted to be held in closed position by a catch 29 to control the Outlet of material from the chute.

In order to draw the wagon and excavating- 6 5 machine over the ground, I preferably provide a windless 29, connected by a cable 30 with suitable support. (Not shown.)

The apron 23 forms an extension of the runway 22 to rest upon the ground. rIhe chains 17 ,'as shown, allow the scoops to be moved away from the chains 12 in excavating.

As will be seen by the drawingsjthe runway and supporting-framework of the excavator is preferably constructed of metal bars, connected to form a skeleton construction.

It will be evident that the arrangement of operating mechanism and the particular construction of framework, &c., may be more or less modified without departing from my invention, the scope of which is defined in the claims.

Having now described my invention, what'I vclaim as new, and desire to secure by Letters Patent, is-

1. In a machine of the class described, the combination with a suitable framework, of an inclined `runway having fulcrum support therein, endless chains carried by said runway, scoops connected by auxiliary chains to said endless chains, means for actuating said endless chains, and an adjustable connection between said runway and framework.

2. In a machine of the class described, the

combination with a suitable framework, of an l inclined runway having fulcrum support therein, endless chains carried by said runway, scoops connected by auxiliary chains to said endless'chains, a' discharge-chute supported in the framework below the inner end of said runway,and means for actuating said chains.

3. In a-rnachineof the class described,..the

5 combination with a suitable framework, of a downwardly inclined runway having fulcrum support in said framework, endless chains carried by said runway, scoops connected with said chains, a guideway supported IO below the upper end of said runway, a hinged apron at the lower end of said guideway,a discharge-chute supported in said framework adjacent to the inner end of said runway, and means for actuating said chains.

In testimony whereof I affix my signature in I 5 presence of two witnesses.
